HID Keyboard and/or multifunctional HID can be used now for the MSX keyboard entry. Plug and play is fully supported as well as wireless keyboard transceivers. From now on you can connect your fancy PC/MAC USB keyboard to your MSX machine by using Procyon.

However, now the architecture has the ARM Cortex M3 system controller handling 2 USB ports, SDHC card interface, MIDI and service OLED LCD display.

FPGA and ARM FW images can be uploaded via USB interface or auto-programmed via SDHC. One USB port is TYPE A (HOST) and the other is USB OTG (TYPE A/B). Both ports can have USB HID devices (Keyboard/mice/gamepad), mass storage and/or wireless. USB HUBs are not supported by the current ARM FW.

Also the HDMI genlock now is on the board together with the composite video/CSYNC socket.

The final VCO architecture was selected, designed and tested. It is not an all solid state VCO though. But despite multitude of components, it offers an excellent low noise performance, temperature stability. The tuning range is superior to the original discrete design. Increasing the tuning range reduced drastically the PLL lock time. Now it takes 2 seconds to achieve a full lock on the VDP scan mode change.

No spurs, ultra clean!

And a very important property of this design – it all works without a shield!

New solid state VCO (Voltage Controlled Oscillator) design will replace a fully discrete VCO (on the left card) in order to improve the DFM (design for manufacturability). VCO is a heart of the HDMI genlocked PLL module, which performance is essential to the stability and quality of digital image.

However, still quite a low of work is required on the VCO itself, due to the very high level of phase noise.

Procyon now runs MSX2 titles. MSX2 VDP V9938 chip is implemented including the industry first “HDMI zero delay multi mode Genlock”! The full on the fly support of 50/60 Hz progressive and interlaced video modes was added.
